--- Comment #1 from Nikolay Sivov bunglehead@gmail.com 2009-09-09 05:34:44 --- Some updates here.
On current Wine (at dad99e2aa943bf63e06b0c1be089411131fdd864) actually allows this demo to render. Solid lines, dashed and curves looks fine but doesn't use anti-aliasing. Circle nodes have wrong colour - yellow instead of dark blue (? or something like that) to white gradient - it's a lack of full gradient brushes support. Arrow line endings are also missed.
Maybe this one could be closed, with a couple of new reports.
P.S. Benchmark currently shows ~100 ms faster for Wine :). So some gap still exist for anti-aliased curves and gradients (if benchmarking does it right on Wine of course).
